Spiral duct reducer galvanized | Ø 100–450 mm → Ø 80–400 mm selectable | with rubber lip seal

The spiral duct reducer made of galvanized steel sheet enables professional connection of ventilation pipes of different diameters. Thanks to the symmetric design and rubber lip seal on both sides, it creates an airtight and secure connection – entirely without additional sealant.

The male/male design ensures quick and easy installation directly between two spiral ducts. The reducer is perfect for pipe-to-pipe connections, where the cross-section of the ventilation system needs to be adjusted.

Available with inlet Ø 100–450 mm and outlet Ø 80–400 mm – simply select the desired size combination when purchasing. Made of durable, corrosion-resistant galvanized steel for long-lasting and reliable use.
